Al-Anfaal 8:72

Those who believed, migrated, and fought with their wealth and their lives in the cause of Allah, and those who provided [the migrants] with shelter and help – they are allies of one another. As for those who believed but did not migrate, you have no obligation to protect them until they migrate. But if they seek your help in religion, it is your obligation to help, except against people with whom you have a treaty. And Allah is All-Seeing of what you do.

Indeed, those who have believed and emigrated and fought with their wealth and lives in the cause of Allāh and those who gave shelter and aided - they are allies of one another. But those who believed and did not emigrate - for you there is no support of them until they emigrate. And if they seek help of you for the religion, then you must help, except against a people between yourselves and whom is a treaty. And Allāh is Seeing of what you do.

72. Verily, those who believed, and emigrated and strove hard and fought with their property and their lives in the Cause of Allâh as well as those who gave (them) asylum and help, - these are (all) allies to one another. And as to those who believed but did not emigrate (to you O Muhammad صلى الله عليه وسلم), you owe no duty of protection to them until they emigrate[7]; but if they seek your help in religion, it is your duty to help them except against a people with whom you have a treaty of mutual alliance; and Allâh is the All-Seer of what you do.

[7] (V.8:72): See the footnote of (V.3:149).

Lo! those who believed and left their homes and strove with their wealth and their lives for the cause of Allah, and those who took them in and helped them: these are protecting friends one of another. And those who believed but did not leave their homes, ye have no duty to protect them till they leave their homes; but if they seek help from you in the matter of religion then it is your duty to help (them) except against a folk between whom and you there is a treaty. Allah is Seer of what ye do.
